Thank you for your input. We are contacting Cisco to get their input on this, but we have to explore RH options if any as well. Would there be a way to enable NIC (network device on the server) and make it IGMP aware somehow. In essence how can I make NIC's manage IGMP and PIM, is there a way? I know I can make a NIC in Linux become a router, but how do I make it IGMP and PIM aware on each node?
